Forgot a drain plug while winterizing

It was cold out yesterday here in ny and I went out to look at my boat. I noticed I had forgot to remove the front drain plug by the water separator. I have the 5.7l and had removed the block and manifold plugs and all the hoses but seems I either forgot the front plug or for some reason put it back in. I took it out today and had a drop or two of water come out. I put all plugs and hoses back and poured antifreeze into block thru top hose. It instantly came out open plug hole so I put plug back in. I would assume there’s no ice in motor or the coolant wouldn’t have come out. Any thoughts?
